Re: 6.5 wsm, please educate me.
I had to build myself a 6.5 WSM as well but unlike most you are hearing about mine is for big game hunting and is chambered in the Rem XP-100 bolt action handgun. I use this for deer hunting out to 400 yards(farthest so far anyway).
It has a Lilja 1-8 twist 3 groove and it shoots the heavy match bullets extremely well but when I was doing the barrel break in I used the 120 gr Ballistic Tip and for just over 35 three shot groups at 100 yards for the break in and load development, this handguns largest three shot group measured right at .882" and well over half have been solidly under 1/2" at 100 yards.
Groups at 300 yards also hold 1/2 moa easily with this bullet loaded to a very warm but not excessively high pressured load at 3100 fps out of the 15" handgun.
To be honest, all the 6.5 WSMs I have built to date have all been handguns and all would out shoot most rifles on average out to 300 yards.
Obviously this is a very accurate round, Chris mentioned his wife kicking some rear in comp with a rifle he built for her.
Still if you are looking for high volume shooting, I would strongly recommend dropping down to the smaller capacity 6.5 rounds as you will get much better barrel life in something like a 260 Rem or 6.5-284.
All are equal in accuracy potential in my opinion, they all flat out shoot when put together properly.
If your looking more for a big game rifle, do not overlook the great 6.5-06 AI. It is only slightly behind the 264 Win Mag and nearly identical to the 6.5 WSM in ballistic performance.
Plus it will feed vastly better then the WSM or the Win Mag. IT is also EXTREMELY easy to load for and in a well built rifle it is one of the easiest chambering to shoot little groups with, even in a sporter rifle.
I am working on one as we speak so if your interested in its performance let me know and I will get you some information.
Basically it comes down to your intended use for the rifle, that will determine which way you should go in case capacity and what amount of barrel life you could accept.
